COMBINATION-TOOL.

SPECIFICATION formng part of Letters Patent No. 638,'759, dated December 12, 1899.

Application filed' September 18 x 1899. Serial No. 730,'932. (NonodeL) To all whom it may conccrn:

Be it known that I, GEORGE W. PRINZING, a citizen of the United States, residing at Bartlett, in the county of Willianson and State of Texas, have invented a new and useful Combination-Tool, of which thefollowing is a specification.

My invention reiates to combination-tools, and more particularly to wrenches which are adapted for nse as pipe-cutters and pipewrenches by the addition thereto of interchangeable attachments,and has forits object to produce a tool which can be readily adapted for one use or another and is equaily efficient for either.

My invention consists in the combination and improved Construction of parts of a wrench, as will be hereinafter more fully set forth.

Referring to the accompanying drawings, in which the same reference-numeral indicates a corresponding part in each of the Views in which it occurs, Figure l is an elevation of a wrench embodying my invention, the pipecutting attachment being shown in dotted lines. Fig. 2 is a longitudinal sectional View of the same, the pipe-wrench attachment being shown in dotted lines. Fig. 3 isa broken perspective view of a portion of the handle; and Figs. 4 and 5 are perspective views of the pipe-cutting and pipe-wrench attachments, respectively.

In practicing my invention I recess the rigid jaw 1 longitudinaily and provide its rear end with two rearwardly-extending arms 2 and 3, each of which is provided with a lip or shoulder 4 and one of which is longer than the other. The movabie jaw 5 has its shank perforated iongitudinally and screw-threaded, so that it can be drawn back and forth within the recess of the rigid jaw by the rotation of the handle 6. The handle of the wrench has its shank screw-threaded to engage with the screw-threaded perforation of the shank of the novable jaw, and has its intermediate portion provided with two annuiar grooves 7 and 8 to register with the lips upon the arms of the rigid jaw to hold the handle and rigid jaw in fixed longitudinal arrangement with each other. The front wall of the forward groove is cut away to the botton of the reoess, as shown at 9, to permit of the parts being assembied.

Iu assenbling the parts of the wrench the shank of the handle is inserted into the re- 'cess of the rigid jaw at such angle as to permit the grooved portion of thehandle passing in under the lip on the longer arm, the cutaway portion of the handle permitting that end to pass in over the lip on the short arin. As soon as the handle has been inserted, so as to cause the grooves to register with the lips, the shank of the novable jaw is inserted into the opposite end of the recess of the rigid jaw until the end of the shani( of the handle will enter the recess in the n ovabie jaw. The handle is then rotated to cause its screwthreaded shank to enter the recess of the shank of the movable jaw, and thus move said jaw back and forth relativeiy to the fixed jaw as the handle is rotated in reverse directions.

I prefer to extend the head of the jaws in the opposite direction from the usual tapered points and provide one of thenwith anoverhanging portion 10 and the other one with a recess ll. In the drawings I have shown the head of the movable jaw provided'with an overhanging portion and the fixed jaw with a recess. Removably seated within the recess may be placed a rotary pipe-cutter 12 or a pipe-jaw 13, each of which is provided With lateral projections 14 and 15, respectively, which fit within slots 16 in the walis of the recess. The bottom of this slot is preferably eXtended at an angle a short distance to the rear to pernit of the projections on the attachments fitting therein to hold then against accidental displacenent.

The projections on the rotary cutter forn an axle, on which it rotates, and the oorner of the jaw at the recess is cut away at an incline, beyond which the periphery of the cutter projects for engagement with the pipe when held by the overhanging portion of the movable jaw. The head of the pipe-Wrench attachment is provided with a shou1der17, which is preferably inciined to engage with said inclined portion of the fixed jaw Whenthe rear portion is seated within the recess 11.

NVhen it is desired to use my wrench as a vise, the rigid jaw is firnly Secured in a fixed IOO position in such manner as to leave the mov- I dinal screw-threaded perforation, and a hanable jaw and the handle free to be operated, as above described. By arranging the inclined points of the wrench Upward it can be used as a vise having file edges, and by securing it in the reverse position it can be used as a pipe-cutter or a pipe-wrench, according as to whether the cutter or the pipe-wrench attachment is seated within the recess.

As the wrench proper conprises but three elements the two jaws and the handie-itis evident that it can be mannfactured very cheaply and that it is compact and very d nrabie. The use of the attachments with the jaws rendere the wrench capable of use as a combination-tool of wide scope and utility.

Changes in the form, proportion, size, and minor details of Construction may be made within the scope of the appended clainiswithout departing from the spirit or sacrificing any of the advantages of the present invention.

Having thus described nyinvention, what I clain is- 1. In a wrench, the combination, with a longitudinally-slotted fixed jaw, the rear end of which is provided with eXtended arms, one of which is longer than the other one, and the end of each is provided with a lip, a movable jaw, the shank of which fits within the fixed jaw and is provided with a longitudle, the shank of which is screw-threaded and the intermediate portion is provided with annnlar grooves in position to receive said lips when the parts are assennbled, the front wall of one of said grooves being cut away.

2. In a wrench, the combination, with a longitndinally-recessed rigid jaw, the head of which is extended and provided with a recess, the side wails of the recess being cutoff at an angle, and each provided with an angular slot extending froni the cut-off portion, of a inovable jaw, the head of which is eXtended and provided with an overhanging portion the shank of' which fits within the longitudinal recess of the rigid jaw and is provided with a screw-threaded perforation, a handle, the shank of which is screw-threaded and the intermediate portion is interlocked with the rigid jaw, and an attachment adapted to fit within the recess in the head of the rigid jaw each side of which is provided with a lateral projection to fit within the respective slots in the side walls of the recess. r

In testimony that I claim the foregoing as my own I have hereto afixed my signature in the presence of two witnesses.

GEORGE W'. PRINZING.
